So I have a mailchimp email that goes out and shows the latest posts that have been made on the site. The users on the site all have gravatars and I want to include that in the rss feed so that I can point the mailchimp image reader to them.

I have tried using snippets like:

<?php echo get_avatar( get_current_user_id(), 48 ); ?>


<?php echo get_avatar( get_author_email(), 48 ); ?>

and adding that to the rss template in /wp_includes (I would love to do it in functions.php but honestly I just want it to work for this one site so I don't care how I get it done).

It's curious because when I do searches I can only find people trying to figure out how to remove it instead of insert it... I am at a loss.


The point is, that the format have no tags for a image to a user. You must use a other tag to inlcude the avatar of a author, not the author tag. The author tag is only for a string, not markkup or images. But you can add content ot the desciption and this is easy on the filter the_content_feed.

A small example, there add content to this part in the feed.

add_filter( 'the_content_feed', 'fb_plugin_function_name' );
* @param  $content Content of post
* @return string
function fb_plugin_function_name( $content ) {

   $content .= 'Total ' . str_word_count( $content ) . ' words';
   return $content;
  • Not entirely following what you are suggesting. I found this snippet: / Put post thumbnails into rss feed function wpfme_feed_post_thumbnail($content) { global $post; if(has_post_thumbnail($post->ID)) { $content = '' . $content; } return $content; } add_filter('the_excerpt_rss', 'wpfme_feed_post_thumbnail'); add_filter('the_content_feed', 'wpfme_feed_post_thumbnail'); do you know how I could modify this for a gravatar post? – irishcoffee Jan 30 '13 at 21:46
  • yes, but the thumbnail have a other job. It is a enhancement for the post content, the avatar is a identify for a auther. A feed is xml, a semantic markup and each tag have a description from the definition. Your code is like the same as my example inside the answer. But I will write abiut the topic, there is fine, that you think about the job of the tag inside the xml of feed. You can add a avatar to the content, but it have no semantic importance. – bueltge Jan 31 '13 at 19:22
